    Feko works with linear frequency domain solutions. You can import Spice circuits, but only a subset of those. This is described in the appendix of the Altair_Feko_User_Guide.pdf in the help folder of Feko.

    So the above won't work for non-linear devices such as the Schmitt trigger. However, you can apply the time signal obtained through the Schmitt trigger after solving the model in POSTFEKO through the time analysis functionality. You must solve the model with sufficient frequency bandwidth, number of samples, etc to be able to accurately represent the time signal. This is described in section 3.13 Time Domain Results.
